| dc.description.abstract | 利用MATLAB軟體輔助，選擇合適的地震事件規模最小值，將地震事件之座標顯示於台灣圖面上，並且由圖面上的點尋找地震弧，若完成不了兩條弧線的交叉則將顯示規模下修，直至一個完整的地震圓弧交叉出現為止。依交叉型態可分為主地震圓弧交叉以及主雙凸交叉，組成交叉之地震事件規模通常最小值在5.0以上，最大值可達7.0。
主地震圓弧交叉及主雙凸交叉可視為地殼的中兩個應力集中區域交互作用之顯示器，本論文研究時間範圍從1976年12月到1989年12月，並依交叉類型、均勻度及總能量大小個別分析之。目的為研究此時間區間台灣本島及離島區域的主地震圓弧交叉及主雙凸交叉與附近大地震之時間和空間關聯。 | zh_TW |
| dc.description.abstract | We select an appropriate minimum magnitude of seismic events to display the coordinates of the seismic events on the Taiwan map by MATLAB. And then we try to find the strongest intersection of circular arcs of earthquakes from the points on the map. If no intersection can be found, the magnitude will be reduced until we find the strongest intersection of circular arcs of earthquakes(SICAE). According to the pattern of the intersection, it can be divided into the SICAE and the double-convex SICAE. The minimum value of the magnitude of the seismic events that constitute the intersection is usually around 5.0, the maximum value may reach the scale of 7.0.
SICAE and the double-convex SICAE can be regarded as the indicators of the intersections of stress concentration of the crust. The time range of this thesis is from December 1976 to December 1989. The SICAEs will be analyzed individually according to the type, uniformity and the sum of the released energy of the key events of each intersection. The purpose of this analysis is to study the temporal and spatial correlations between the SICAE (and the double-convex SICAE) around Taiwan and the strong earthquakes nearby. | en_US |
